You likely have a dirty Idle Air Control Valve (IAC). The first thing to do is clean it to see if the problem is corrected,

My '08 Heritage can have an erratic idle too. Sometimes it's crazy high and other times it stalls out. I clean the IAC often and changed the TPS and it still does it. I have just learned to live with it...

My 03 does that. Different idle speeds at times. Nothing drastic.
It's never stalled out. Been that way since day one.

Interesting. My carbureted bikes always idled the same speed.
